Problem
A cylindrical bucket has an internal volume of 1.0×10−2m3. It is filled with dry sand whose grains can be approximated as spheres of diameter 5.0×10−4m. Because of void spaces, sand grains occupy only 60% of the bucket’s volume. The order of magnitude of the number of grains that can fit into the bucket is
(a) 107
(b) 108
(c) 106
(d) 109
